In a molecule there will always be integer numbers of a certain atom, and you can never have 3.5 oxygen atoms or 2.493 chlorine atoms in a compound. Atoms are singular units of molecules. Therefore a ratio of integers is always present for all types of atoms in a molecule.
Dalton's atomic model incorporates this idea.
Yes. You can't have a fraction of an atom.
Yes, eg. H2O is water with two hydrogen atoms (2x H in H2O) and one oxygen atom (1x O in H2O).

John Dalton
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.

In general, organic compounds are those compounds which contain both carbon and oxygen, and inorganic compounds lack these atoms. Of couse, this does not always apply, as carbon dioxide and carbon monoxide also contain both these elements and are still labeled as inorganic.
A substance in which all atoms are identical is called an element.
No, because some elements have Isotopes, with the same Proton number but different Neutron numbers. Sometimes therefore, the neutron number can overlap with that of isotopes of other elements. For example, two of Helium's isotopes share neutron numbers with two of Hydrogen's isotopes. Deuterium has 1 neutron, and so does 3He, Tritium has 2 neutrons, and so does 4He. It is the number of protons which determines which element it is.
Elements are often denser than compounds, but not always. In fact the least dense substance known is hydrogen, which is an element.
Organic compounds always contain the element carbon.
Oxygen.
Not necessarily
No, compounds and elements are not always solids. For example, hydrogen is a gas.
elements
There is no element that is always found in inorganic compounds. However, organic compounds always contain carbon and hydrogen, so they would not be found together in an inorganic compound.
Organic compounds always contain Carbon and Hydrogen. Most organic compounds contain elements like Oxygen,Nitrogen,Phosphorus and sulphur. Organic compounds are found in living things.

carbon and hydrogen
Any element that's not a noble gas has to form compounds, because all non-noble elements have to fill its outer orbital and the only way they can do that is to form compounds--even with themselves, like H2 or O2.
